Three times in the past three years I've bought a complete set
of rubber foot protectors for the wooden chairs that are slid
day in and day out on the tile floors.

I first bought the dark brown rubber chair leg protectors
from Home Depot; then the black protectors at Lowes; and
finally the cream colored rubber chair leg protectors at
ACE Hardware.

They all crack and simply fall apart.

Do they make a rubber chair leg protector that won't
fall apart in a year? Where can I get them?
